8  * This driver is based on the 'USB Mass Storage Class' document. This
9  * describes in detail the protocol used to communicate with such
10  * devices.  Clearly, the designers had SCSI and ATAPI commands in
11  * mind when they created this document.  The commands are all very
12  * similar to commands in the SCSI-II and ATAPI specifications.
13  *
14  * It is important to note that in a number of cases this class
15  * exhibits class-specific exemptions from the USB specification.
16  * Notably the usage of NAK, STALL and ACK differs from the norm, in
17  * that they are used to communicate wait, failed and OK on commands.
18  *
19  * Also, for certain devices, the interrupt endpoint is used to convey
20  * status of a command.
